Abstract

This paper describes experimental results on the utilization of some Korean oak woods for whisky aging barrel. Some anatomical characteristics as vessel diameter, ray spacing, ray height, existence of tyloses, water absorption and color change of alcohol during immersing of wood samples were examined. The oak woods used in this study were ring-porous. The type of ray was a compound ray consisted of uniseriate ray and broad ray. The ray parenchyma cells were almost procumbent, tyloses were presented in white oak(Quercus aliena, Quercus variabilis, Quercus dentata, Quercus mongolica), but absented in red oak(Quercus rubura). Density of wood samples decreased during immersing in alcohol. Alcohol color in Quercus dentata and Quercus aliena presented more darker than other samples. Water absorption of sapwoods was higher than that of heartwoods. Especially, red oak showed more higher water absorption than white oak. Consequently, Korean white oak woods can be used as the whisky aging barrel.
